Embodiment Construction

[0038] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0039] It should be noted that when an element is referred to as being “fixed” or “disposed on” another element, it may be directly on the other element or it may be indirectly fixed or disposed on the other element through a third component. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or it can be indirectly connected to the other element through a third element.

[0040] It should also be noted that the orientation terms such as left, right, up, and down in this embodiment are only relative concepts or refer to the norm...

Abstract

The invention relates to the technical field of electronic products, and provides a loudspeaker and a headset. A horn bracket, a magnetic circuit system and a vibration system are comprised. The horn bracket is used for providing a through hole used for accommodating the magnetic circuit system. The magnetic circuit system comprises an inner magnetic ring and outer magnetic ring which sleeves the inner magnetic ring. The inner magnetic ring and the outer magnetic ring share the same axis. A gap is between the inner ring surface of the outer magnetic ring and the outer ring surface of the inner magnetic ring. The magnetic poles of the inner magnetic ring and the outer magnetic ring are different. Magnetic force lines formed by the inner magnetic ring and the outer magnetic ring in the gap are radially arranged. The vibration system comprises a sound film, a voice coil with one end connected with the sound film, and a coil which is connected with the other end of the voice coil. The coil is placed in the gap. The sound film is connected with one end part of the horn bracket. According to the design of the magnetic circuit system, magnetic flux leakage and hysteresis loss are reduced; the magnetic force lines are uniformly and symmetrically distributed; distortion is reduced; and true sound is restored to show the sense of reality.

Description

technical field [0001] The invention relates to the technical field of electronic products, in particular to a loudspeaker and earphones. Background technique [0002] With the continuous improvement of living standards, people are under increasing pressure from work and life, and music has become one of the effective ways for people to relieve pressure. As earphones are constantly updated, people's requirements for the sound quality of earphones are becoming more and more stringent. [0003] The speaker is the sound-generating component of the earphone, and the key design of the speaker to control the sound effect is the design of the magnetic circuit. The current magnetic circuit structure is mostly an internal magnetic structure, and the distribution of the magnetic force lines is uneven and asymmetric. user experience. Contents of the invention [0004] The object of the present invention is to provide a loudspeaker and an earphone, aiming at solving the problem of u...
